Hi, all I am inspecting a process/thread in the android-platform(FROYO). I found weird thing that there is two surfaceflinger thread. I know the first SurfaceFinger start point at booting time but can't find the second SurfaceFlinger start point. My question is (1) Where is the second SurfaceFlinger started ? (2) What does the second SurfaceFlinger do ? (What is the 2nd SurfaceFlinger's role?) Does anyone know this? I attach my system log below. Thanks for your attention.
